Note: Country codes, area codes, and local phone numbers all vary in length from country to country. For instance, country codes can be 1-, 2-, or 3-digits long - e.g., +1 for USA, +44 for UK, +971 for UAE / Dubai.

2. Dial destination country code: &nbspccc

Written phone numbers sometimes include the national long distance dialing codes along with the local phone number. The most common long distance dialing code (or 'NDD') is '0', but there are others. Some smaller countries don't use them at all. If your local phone number starts with a '0', it is probably best to remove it.

The NDD for the USA and Canada is '1' which is the same as their country code. For inbound international dialing, use only a single '1' to represent the country code.

4. Dial local area code / city code: &nbspaaa

If the country you are dialing uses area codes / city codes, you will need to dial it. Some smaller countries do not use area codes. And in some other countries, the area code is 'built' into the local phone number and won't really be distinguishable.

5. Dial destination local phone number: nnnn nnnn

The format of local phone numbers varies widely around the world. You will need the correct local phone number to complete your call.
